GASKET.

Application filed November 41, 1922. Serial No. 599,102.

To aZZ Iwhom, it may cmwern:

ALD, a citizen of the United States, residing at Torrington, in thecounty 'of Litchfield, State of Connecticut, have invented certain newand useful Improvements in Gaskets, of which the followingl is -aspecification.

The invention. relates to* gaskets and more.

particularly l'to a.gasket for th'e manifold of automobile enginesof'the 'Ford type.

The vobject of the invention is to provide a gasket in -which there area plurality of openingsto register with 'the ports of a Ford engine andtheLmanifold, so that all six ports may be packed by either one or twoof the gaskets instead of a separate gasket, for ever port; the twometallic sheets or plates o each gasket being bound together bythimbles, each having flanges overlying opposite sides of the sheets andprovided With an integral tubular guideforming extension.

This object I aecomplish by the construction shown in the drawing, inwhich- Figure 1 shows a face view or plan of the gasket having threeports or openings; Fig.2 is a cross section on the line 2 2 of Fig. 1; r4

Fig. 3 is a perspective of one of the thimbles;

F ig. 4 is aface view or plan of a gasket having six ports or penings.

The gasket is forlned of two superposed 35 plates 1, 1, preferably ofcopper provided With registering central and end port openings orapertures 2, 2, and with bolt openings 3, 3 between the central and endopenings. Between these two plates 1, 1 lies an 40 asbestos sheet 4,similarly apertured.`

The copper and asbestos sheets are bound together by theone part sheetmetal thimblesI 5, also preferably of` copper. Each thimble 5 is forniedwith an external flange V"6 between its ends to engage the outer surfaceof one plate`1, and one end of the thimble 5 is then spun or' bent overthe outer surface of the other late 1 to form the flange 7. This leavest e other end of the one piece thimble 5 with an extension forming an'ammlar guide flange 8. These guide flanges 8 enter the engine ports andBe lt known that I, PATRICK J. Frrzonnserve to hold the gasket inposition While themanifold is being bolted in place. In order to preventbending of the `,guide flange 8, the outer edge thereof is bent inwardlyupon itself, as shown at. 9, so that there is a double thickness ofmetal at this point.

Three ports may be simultaneously packed by a single gasket.

VVhile the A gasket shown is especially adapted for' Ford engines, themain feature of Vthe one piece, double flanged securingr thimble withits integral guide flange may be employed advantageously in othergaskets. I-Iowever, it is highly advantageons to have a gasket Whichwill cover the space between the manifold and three ports instead of aseparate one for every port.

In Figure 4 the gasket has six openings or apertures 2, 2, bolt openings3 and thimbles 5, formed exactly as in Figs. 1 and 2.

This six-ported gasket is adapted to register With all six engines and'manifold ports.

Having thus described my invention, What I claim as new and desire toSecure by Letters Patent, is:

A gasket for manifolds comprising superimposed apertured metal plates,an intel-niediate layer of aperturcd packing material. and one-piecethimblcs for securing the plates of the gasket against the parkingmaterial. each thimble having at one end thereo'f a fiange overlying theedge of the plate around the apel-ture in which the thimble is insertcd,said thimble being of considerably greater length than th` thinkness ofthe parking and plates so as to project from the face of the gasket forentering the same in the ports When applied to an engine, said thimbleintermediate its end and said flange being bent so as toform aprojecting flange which is substantially parallel with the flange on theend of the thimble, and so disposed as to clamp the opposite face of thegasket from that engaged by said flange on the end.

In testimony whereof, I aflix my signature.

- PATRICK J. FITZGERALD.
